The VP 417-32 is a vial rack made from Polypropylene and will accommodate 32 vials or other vessels that have a diameter less than 16 mm. The depth of the hole is 20 mm. The racks dimensions are to the SBS standard - the same as a microplate (127.76 mm long by 85.48 mm wide and 25.4 mm tall) so it fits into the deck nests on all robot platforms.
